+ Regenerate all initramfs images at the default location with the kernel
+ versions found on the system. Additional parameters are passed through.
+
+**--loginstall _<DIR>_**::
+ Log all files installed from the host to _<DIR>_.
+
+**--uefi**::
+ Instead of creating an initramfs image, dracut will create an UEFI executable,
+ which can be executed by an UEFI BIOS. The default output filename is
+ _<EFI>/EFI/Linux/linux-$kernel$-<MACHINE_ID>-<BUILD_ID>.efi_. <EFI> might be
+ _/efi_, _/boot_ or _/boot/efi_ depending on where the ESP partition is mounted.
+ The <BUILD_ID> is taken from BUILD_ID in _/usr/lib/os-release_ or if it exists
+ _/etc/os-release_ and is left out, if BUILD_ID is non-existant or empty.
+
+**--no-machineid**::
+ affects the default output filename of **--uefi** and will discard the <MACHINE_ID>
+ part.
+
+**--uefi-stub _<FILE>_**::
+ Specifies the UEFI stub loader, which will load the attached kernel, initramfs and
+ kernel command line and boots the kernel. The default is
+ _$prefix/lib/systemd/boot/efi/linux<EFI-MACHINE-TYPE-NAME>.efi.stub_
+ or _$prefix/lib/gummiboot/linux<EFI-MACHINE-TYPE-NAME>.efi.stub_
+
+**--kernel-image _<FILE>_**::
+ Specifies the kernel image, which to include in the UEFI executable. The default is
+ _/lib/modules/<KERNEL-VERSION>/vmlinuz_ or _/boot/vmlinuz-<KERNEL-VERSION>_
